As a follow-up to the Sac Transportation & Climate Workshop big idea of bike superhighways, I was curious about how the proposed alignments matched with low income and high minority communities in Sacramento.

The map presented at the workshop is low resolution, but I decided to see if I could reproduce the routes, using a combination of the city’s existing and proposed bike network data, the road network where the proposals didn’t seem to match the bike plan, and just plain guessing. You’ll notice gaps and places where the alignment may not be correct, but overall it provide an good impression of the proposal. It is interesting that some of the on-street low-stress bikeways routes are not in the current city bike master plan.

The demographics data for low income high minority communities is from SACOG’s Environmental Justice Areas. This is just one of many possible comparisons. Population density and employment locations would also be interesting. I don’t know what demographic information the city used to come up with the bike superhighways proposal.

The map is below, and pdf. The red lines are the bike superhighways, the blue lines are the ‘on-street low stress bikeways’ that provide to some degree the connection from the bike superhighways to the central city.

Does the proposal serve the people who need to be served? Meh. To some degree. The Sacramento Northern Parkway, at upper right, probably does the best. It is an existing separated path (Class 1) that does need upgrades at road crossings but otherwise is ready to go. The Jackrabbit Trail at the upper left does serve high minority areas, but not low income. It is mostly an existing route, with some gaps and several completely unsafe roadway crossings. The south area is a major bikeway desert, of course, due to both city and county disinvestment and transportation discrimination, and this proposal does little to correct that.
